The nurse is preparing to administer Insulin Lispro (Humalog) to a client with Type 2 Diabetes Mellitus for carbohydrate coverage. The nurse understands the injection should be administered:

A. "Diet, exercise, and oral medications can be effective. I will ask the physician to prescribe Metformin":
Explanation: This statement is not accurate for type 1 diabetes. Type 1 diabetes results from the inability of the pancreas to produce insulin, so oral medications like Metformin, which work to increase insulin sensitivity or reduce glucose production in the liver, are not effective. Insulin replacement is the mainstay of treatment for type 1 diabetes.

B. "Your body does not produce insulin, and the only treatment is injected insulin":
Explanation: This is the correct statement. In type 1 diabetes, the pancreas does not produce insulin or produces very little, and insulin cannot be taken orally because it would be broken down in the digestive system. Therefore, injections are the primary and necessary mode of insulin delivery.

C. "Glucophage can help your body better utilize the insulin secreted by the pancreas":
Explanation: This statement is more applicable to type 2 diabetes, where the pancreas may still produce insulin, but the body's cells are resistant to its effects. In type 1 diabetes, the issue is a lack of insulin production, so medications to improve insulin utilization are not relevant.

D. "Initially, you will need injections, but after your body adjusts to the insulin, you can switch to Metformin":
Explanation: This is not accurate for type 1 diabetes. The need for insulin in type 1 diabetes is not something the body adjusts to over time. Insulin is a lifelong requirement for individuals with type 1 diabetes, and it cannot be replaced by oral medications like Metformin.

A. Stress has likely caused an increase in the client's blood sugar levels:
This statement is accurate. Stress, especially related to surgery, can lead to increased levels of stress hormones, such as cortisol and catecholamines, which can elevate blood sugar levels. Surgery is a physiological stressor that can impact glucose metabolism.

B. The client's volatile fluid balance surrounding surgery has likely caused unstable blood sugars:
This is the most appropriate choice. Surgery, anesthesia, and changes in fluid balance can affect blood glucose levels. The stress response to surgery can lead to fluctuations in blood sugar, and patients may need insulin during this period.

C. The client has likely overstimulated her ability to control her diabetes using non-pharmacologic measures:
This statement is not accurate. Overstimulation is not a common cause of the need for insulin in the context of surgery. The stress and physiological changes associated with surgery are more likely contributors.

D. Alterations in bile metabolism and release have likely caused hyperglycemia:
While alterations in metabolism can impact glucose regulation, in the context of surgery, the primary factors are the stress response, changes in fluid balance, and potential alterations in the ability to eat or drink normally rather than specific effects on bile metabolism.
